Sponges

Red Beard Sponge

Sponges grow at all depths, and in brackish and freshwater also. They may occur as thin encrusting coatings on rocks and wood, or as long thin branching fingers attached to the bottom, or in the typical rounded form that has been used for centuries as ... a sponge!

The Red Beard Sponge Microciona prolifera is the commonest and most colorful of several sponges that grow in the region.

They are the most primitive of multi-celled animals, lacking distinct tissues and organs.
